Coastal settlement [3] - p. 2 | Campaign - southern way JA: Crossfire Guide

The last point, on the south of the map, may be very challenging. I recommend to get on the roof and place between two ladders leading upstairs, to have time aim at climbing enemies. Watch out on the enemy with the blade.
Alternately place in a way which allows you fire at enemies located in different directions.
Enemies from the inside you can lure out or shoot through the windows.
When you take over all region, return to the main map and expect the attack from Khadwan.
With that knowledge, you can place your mercenaries on the good positions before enemies get here. Doing so, you can eliminate them very easily.
Or set up the anti-personnel mines if you know their future path (red dots on the screen).
